Update: RisingHF Gateway RHF0M301 with Loriot Community Network

It’s been about a year since I posted an unofficial manual for getting the Seeed Studio 915 MHz RisingHF Raspberry Pi gateway up and running with Loriot. In that time, I had hoped that there would be more resources available for enthusiasts to find information about setting up gateways, nodes and sensors. However, it looks like complete and reliable information is still hard to come … Continue reading Update: RisingHF Gateway RHF0M301 with Loriot Community Network

Sniffing GSM with SDR

I’ve been fascinated by software defined radio (SDR) for years but investigating the GSM cellular network has always been just a little too challenging and slightly out of reach. All of that changed earlier this year when someone finally posted a workable, step-by-step guide for decoding (but not decrypting) cellular (GSM) radio traffic.

The installation that Paik created consists of three rows … Continue reading Video Arbor is Back

Getting Started with Wearables… in 1983

It seems like every electronics company from large to small is introducing a wearable device these days. As seen at CES 2015, it is all the rage to connect some kind of bodily sensor to the internet, pair it with an app and strap it to oneself. Most of these are fitness trackers that detect some combination of distance, speed, or heart rate. I started … Continue reading Getting Started with Wearables… in 1983

My Visit to the 2013 Consumer Electronics Show (CES)

I spent a few days last week at the CES in Las Vegas to learn about the latest trends in consumer electronics, with particular attention to items in the “connected home” category. This was my first time at the CES and everything one hears about the show is true: the exhibit floor is massive, it is impossible to see everything, and the products displayed range … Continue reading My Visit to the 2013 Consumer Electronics Show (CES)
